FLY-BALL GOVERNOR.

Specification ofLetters Patent. Patented Nov. 30, 1909. Applicationfiled February 1, 1909. Serial 1%. 475,386.

To all whom it mag concern:

Be it known that I, MAX HAEBERLEIN, a citizen of the Empire of Germany,residing in New York, in the borough of Manhattan, county and State ofNew York, have invented certain new and useful Improvements in Fly-BallGovernors, of which the following is a specification.

This invention relates to-a fly-ball governor which combines extremesensitiveness with a simple and durable. construction; and the inventionconsists of an inclosed fly-ball governor in which the fly-ball leversare mounted on knife-edges and are acted upon directly by adjustablecounterbalancingsprings in such a way that there is no friction betweenthe springs and the levers, the

levers being linked, independently of the springs, to a verticallyslidable sleeve which is connected to the regulating mechanlsm.

In the accompanying drawings, Figure 1 represents a vertical centralsection of my improved fly-ball governor, Fig. 2' is a vertical sectiontaken on a plane at right angles to the sectional plane of Fig. 1, andFig. 3

is a horizontal section on line 3, 3, Fig- 2.

Similar letters of reference indicate corresponding parts. throughoutthe different figures.

Referring to the drawings, f re resents. the spindle of my improvedfly-bal governor, which is geared to a prime motor of any kindand wh1chfollows the speed-changes of. the same. The spindle f is provided with acentral bore f at its u per end and with slots 1) at opposite sides 0the bored out portion. To the bored out upper end of the spindle f is aplied the conically-fiaring bottom-plate 0 0 a cylindrical casing orshell 0, which bottom-p ate is provided with a central hub 0 adapted tobe screwed or otherwise attached to the spindle, and with acircumferential rim 0 to which the rimmed lower end of the bod} or-mainortion c of the casing or shell 0 lsattached y means of fastening screws0. The to of the casing or shell is made conically bottom-plate, andalso provided with a central hub 0 into which is screwed the threadedpin 0? for maintaining in position-a capplate e, which can be adjustedhigher or lower by means of the threaded pin, which latter is providedwith a square or other head at its outer end forfacilitating theadaring, like the justment of the cap-plate by means of a wrench.

At the interior of the'shell, and at diametrically-opposite points ofthe same, are

arranged two knife-ed ed fulcra g, which are attached by means 0%fastening screws 9 to the inner circumference of the bottom: plate ofthe casing or shell '0, and which engage the recessed apexes of twoangular flyball levers h, which are provided with flyballs of the usualsize at their upper ends and which are pivoted at the inner ends oftheir lower arms to the upper ends of links a, a. The links a, a arearranged beside each other and extended into the bored end ofthe spindlef,"their lower ends being connected by a transverse pin 12 with a sleeve6- which is provided with an exterior grooved collar 6 in which a ring ris placed counterbalanced directly by the springs 8,

without being transmitted to the pivot-pins of the links a, a. Theresultant of the centrifugalforce and the pressure of the springs passesto the fulcra g, g without creating any appreciable friction between thelevers and the fulcra. This arrangement insures a very sensitive andeffective governor. The. knife-edged fulcra are preferably made of steelso as to stand the wear to which they are exposed by the oscillations ofthe fly-ball levers. The casing or shell, and the fly-ball levers rotatetogether, and the speed of the motor is regulated through suitablemechanism actuated by the movement of the flyball levers as they assumethe positionresulting from the centrifugal force and the force of thesprings on. the fly-ball levers.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

,-l. A fly ball governor comprising a rotatable spindle, a sleevesliding on the same, fly-ball levers provided with weights at theirupper ends, a casing, o shell inclosing the fly-ball levers, fulcra atdiametrically-opposite points on the base of said casing or shell, acap-plate supported in the upper part of thecasing, separatecounter-balanclng springs inter osed between the lower arms of thefly-ba 1 levers and the cap-plate, and means connecting the fly-balllevers with the movable sleeve on the spindle.

2. A fly-b'all governor comprising. a ;ro-' tatable spindle having abored out .upper end, a sleeve sliding on said spindle, a casing orshell attached to the spindle, fulcra at diametrically opposite pointson the base of said casin or shell, fly-ball levers swinging on said fuera and rotating with the splnda and shell, a cap-plate supported in theupper part of said casing or shell, separate counterbalancing springsinterposed between the lower arms of the fly-ball levers and thecapplate andpivotlinks extending into the bored out end of the s indleand connecting the lower arms of the y-ball levers with the movablesleeve on the spindle. V

3. A fly-ball governor comprising a rotatable spindle carrying a casin asleeve movable on the spindle, opposite y disposed fulcra in saidcaslng, angular fly-ball levers swinging on said fulcra, a cap-platesupported in the upper part of the casing, sep-' arate. counterbalancingsprings interposed between the cap-plate and the inner ends of thefly-ball levers, and means connecting the fly-ball levers with thesleeve movable on the spindle.

4. A fly-ball governor comprising a 1'0- tatable spindle, a sleeveslidable thereon, an

v gular fly-ball levers having weights at their upper ends and circularrecesses on the upper face of their inner ends, a casing supported onsaid spindle and carrying fulcra on which the fly-ball levers arepivoted, a cap-plate supported in the upper part of said casing andhaving circular recesses in its lower face, counterbalancing-sp-ringsinterposed between the recesses of the cap-plate and the recessesinterposed between the recesses of the capshell inclosing' the fly-balllevers and secured to the rotatable spindle, a fulcra at oppositelydisposed points on the base of the 5,

casing, a cap-plate supported in the upper part of the casing and havinga pair of circular recesses in the lower face thereof,counterbalancing-springs interposed between said levers and said ca-plate with their 61 ends seated in the circu ar recesses of the same,and. means connecting the fiy-ball levers with the sleeve movable onthspindle.

6. A fly-ball governor comprising a rotatable spindle having a bored outupper end, a sleeve slidable on the spindle, a casing attached to thespindle, fulcra at opposite points on the base of the casin angularfly-ball leversvswinging on said ulcra and having Weighted upper ends,and circular recesses on the upper faces of theirinner ends, a cap-platecarrled in the 'upper part of the casing and having a pair of circularrecesses in its lower face, 4counterbalancing-springs plate and therecesses of the fly-ball levers, and pivot-links extending into thebored outend of the spindle and connecting the inner ends ofthe fly-balllevers with the sleeve slidable on the spindle.

In testimony that I claim the foregoing as my invention, I have signedmy name in presence of two subscribing witnesses.
